Java regexes operate on unicode strings, so ".' matches any *character*
There is no regex syntax to match an any "byte" so a regex based approach 
is never going to be viable.

You're best bet is to check the byte count when indexing -- but even then 
you'd need some custom code since things like 
FieldLengthUpdateProcessorFactory are well behaved and count the 
*characters* of the unicode strings.

If you absolutely can't reindex, then you'd need a custom QParser that 
produced a custom Query object that iterated over the TermEnum looking at 
the buffers and counting the bytes in each term -- matching each doc 
assocaited with those terms.
